It will be; obviousthat'thepassage of -pthe liquid, through tortuous paths and the friction of the liquid during this passage will material-1y reduce the velocity or flowing pressure thus eliminating noise.

The form of the invention illustrated in Fig. 3 is substantially the same as that illustrated in Fig. 2 except that three sets of pressure reducing elements have been provided. In this embodiment the ends of the casing are shown at E and F and between these ends are disposed three plates G, H and J. Each of these plates has concentric rings extending from the opposite surfaces thereof which coact with other concentric rings to form tortuous passages for the liquid. It will be obvious that as many sets of pressure re-' ducing elements can be assembled as desired and. that the device shown in Fig. 3 will operate in the same manner as that shown in Fig. l, but will effect a greater reduction in the velocity of the fluid due to the successive action of the pres; sure reducing elements. Each of the plates is provided with a series of openings which are adjustably controlled as to size by plates similar to the plate 3| shown in Figs. 1 and 2.

Figs. 4 and 5 illustrate a slightly different form of the invention. In this embodiment the inlet opening 40 is disposed adjacent one wall of the casing and the outlet opening 4| is disposed centrally of the casing. The end 42 of the casing is provided with parallel ribs 44 which-coact with parallel ribs 46 which extend toward the end 42 parallel to the ribs 44. The ribs 46 are formed on a plate 48 having ribs 50 extending laterally from the opposite surface thereof. Two other plates 53 and 54 are'disposed in the casing between the plate 48 and a plate 49 and are provided with parallel ribs coacting in the manner above described to form tortuous passages. Plate 49 has parallel ribs coacting with ribs on plate 54. The plates 48, 53, 54 and 49 are provided withopenings 55. A plate 45 is disposed between plate 49 and the end 41 of the casing and has a series of openings 51 which are adjustably controlled by a ring 56 having openings 58 therethrough which may register with or partially overlap the open-i ings 5T.

In the form of the invention shown in Figs. 4 and 5 the liquid enters through the opening 40, passes downwardly in the tortuous passage formed between the parallel ribs and 46, thence through the opening 55 upwardly between the next set of coacting'ribs, through the next open ing 55 and thence'successively downwardly, upg wardly and downwardly, leaving the casing through adjustable openings 51 and the outlet opening4|.'

From the foregoing description it will be clear that in each form of'the invention simple and practical means has been provided for reducing the flowing pressure or velocity of liquid passing through the device and it will also be evident that the device can be built up in such a manner as to interpose any desired number of tortuous paths through which the-liquid must pass. The rate of flow can also be regulated by adjusting the size of the openings within the casing through which the liquid must pass a Although certain specific embodiments of the invention have been particularly shown and'described it will be understood that the invention is capable of modification and that changes in the construction and in the arrangement of the various cooperating parts may be madewithout departing from the spirit or scope of the inven- .tion, as expressed in the following claims.
